Patent GB-1373744-A (GB)
Title: Droplet generator and method
IPC: B01J2/02
Filed: 1973-01-09
Abstract: 1373744 Granulating GULF OIL CORP 9 Jan 1973 [14 Jan 1972] 1102/73 Heading B5A [Also in Division C1] Droplet generating apparatus breaks-up a stream of liquid sol. of a fertile or fissionable nuclear fuel material into uniform spherical droplets of predetermined size by imposing periodic pressure pulsations on the liquid to cause corresponding varicose instabilities in the jet stream, these being enhanced by a surrounding concurrent, coaxial fluid flow to break-up the stream into droplets which are subsequently solidified. The liquid sol. is of a viscosity above 10 centistokes. The apparatus comprises a reservoir chamber 34, into which liquid feedstock is fed via conduit 40. A capillary tube 12 is sealed through a bush into the lower end of the reservoir so that the liquid will emerge from the lower end of the tube 28 in a fine stream, the diameter of which is determined by an orifice in an interchangeable insert at that end. The upper part of the reservoir 34 is sealed by a flexible diaphragm 14 which transmits high-frequency pressure variations to the liquid in the reservoir and hence, in the capillary tube, thus causing varicose instabilities 22 in the emerging jetstream 20, which are utilized to break the stream into uniform droplets 26, by means of a gaseous or liquid stream 24 forced through the coaxial tube 72 via ports 78 supplied from an annular manifold 84. The periodic flexure of the diaphragm 14- is obtained by an impinging airstream 56 which is periodically interrupted by a toothed wheel 60, the frequency and amplitude being determined by the number of teeth and the spacing between them respectively (Fig. 1, not shown). A vibrating piston impinging directly upon the reservoir fluid may be used instead. The size and uniformity of the droplets is determined by adjustment of the relative values of capillary orifice, frequency of pulsation and speed of concurrent fluid flow and the Specification discusses the determination of appropriate values. Preferably the periodic varicose instabilities have a wavelength of at least # times the unperturbed jet stream diameter. The droplet production rate may be varied from below 10,000 to over 100,000 per minute. An example sets out suitable dimensions for the apparatus and describes its use with feedstock sols. of thorium oxide; a dispersion of carbon in a solution containing zirconyl and uranyl nitrates; and a solution of uranyl nitrate. The coaxial fluid may be kerosene or carbon tetrachloride. The droplets may be solidified by passage through ammonia into an aqueous solution of ammonium hydroxide and then air dried. The apparatus may be arranged to project the jet stream upwards, the coaxial fluid flow being likewise directed.

Title: Method and apparatus for reducing atmospheric pollution
IPC: F01N13/02
Filed: 1971-01-09
Abstract: 1377501 Treating exhaust gas GILBERT SHAW Ltd 31 Dec 1971 [9 Jan 1971 23 Sept 1971] 1143/71 and 44366/71 Heading F1B A process of removing water of combustion and pollutants from the exhaust gases of an internal combustion engine comprises passing exhaust gases from the engine to a heat exchanger, utilizing ambient air at said heat exchanger to cool the exhaust gases by convection alone below their dew point to produce condensed water of combustion, and separating the condensed water together with pollutants dispersed therein as an unseparated mixture from the residual exhaust gases. An apparatus for carrying out the method comprises a number of hollow plates 1, 1a, 1b, 1c and 1d, each plate consisting of two 24 gauge stainless steel sheets welded together at their edges and along the lines 3 and also dimpled and spot welded at the points 4. Exhaust gas enters at 5, follows a serpentine path through the plate, and then enters the next plate, so that as seen in Fig. 2, the gas follows a zig-zag course from one plate to the next. Emerging from plate 1d at 20 the gas passes through a woven wire mesh entrainment separator 21 into tail-pipe 23. The plates are stated to be each 42 ins by 28 ins. Condensate falls into a receptacle 19 from which it is withdrawn via a drain cock 25. Cooling air is directed between the plates by scoops mounted on the vehicle in which the heat exchanger is fitted. Fan assistance may also be provided. The plates are ¢ in - 1À0 inch apart. The receptacle 19 is of double-walled construction to conserve heat so that the liquid does not freeze. The residual gases are re-heated before discharge to atmosphere by passing them through a double-walled pipe in which they receive heat from the uncooled exhaust gases. In a modification the plates are connected in parallel instead of in series.

Title: Projectiles
IPC: F42B30/00
Filed: 1928-01-13
Abstract: 304,463. Nichols, H. J. Jan. 13, 1928. Projectiles.-An armour-piercing projectile is provided with a specially constructed base plug for sealing the explosive chamber, whereby the the projectile is capable of withstanding the stresses due to an oblique impact in such a manner that tearing away the base of the shell is prevented. This object is attained by so constructing the plug that it is able to yield laterally, whilst its shape is such that explosion of the change expands it so that the plug is not blown out backwards, thus ensuring complete breaking up of the walls of the shell. As shown, the chamber 10 containing the bursting-charge is sealed by a screwed plug 11 having an external central cavity 16 of sufficient depth to render the plug elastic. The cavity may be closed by a plate 17, Fig. 2, and may be filled with a yielding material such as a sand or aluminium. Internally, the plug is preferably hollowed out near the periphery, at 23, forming a lip which expands and seals the base effectively when the charge is exploded by the fuze 15.
